  FWIW, I have a lot of problems with mail and news server connections
  that seem to hang up all the time (with both GNU Emacs and XEmacs). To
  the point that I have added this to my gnusrc:

(defcustom dvl-gnus-kill-server-connections t
  "Whether to kill Gnus server connections immediately after use."
  :type 'boolean)

;; This function is hooked into gnus-get-new-news-hook and
;; gnus-summary-exit-hook in order to prevent hangs.
(defun dvl-gnus-kill-server-connections ()
  "Kill Gnus server connections.
See also the variable `dvl-gnus-kill-server-connections'."
  (when dvl-gnus-kill-server-connections
    (call-process "killall" nil nil nil "gnutls-cli")))

This makes things a little better, like, 50%...
